WOOD CONSTRUCTION
How to plant a pole
The detail in these diagrams assists proper drainage of moisture
that may be absorbed but a wooden pole. A structural engineer must
be consulted for detailed structural requirements. Poles intended for
planting in the ground must be purchased at required lengths, Never
plant a cross-cut end of a treated pole or post into the ground as this
will expose the untreated heartwood to fungal and termite attack
resulting in premature failure.
Buying and using preservative treated timber?
In South Africa treated timber is by law required to comply
with national and compulsory specifications and must
bear marking containing the following information:
South African Wood Preservers Association (SAWPA)
The South African Wood Preservers Association (SAWPA) is a
non-profit association formed in 1980, by the South African wood
preserving industry, primarily to promote timber treatment and
treated timber products. Commercially grown timber in Southern
Africa is mainly of the Eucalyptus and Pinus species, both of which
are not durable. By applying the correct chemicals to these timbers
ensures that the timber performs as if it were durable thereby
giving predictable long life performance.
